Best overall Wordpress theme(s)/framework to meet these requirements?

WARRIOR BROTHERS....

I intend to create multiple sites with different purposes, and I want to purchase a reliable Wordpress template or three (if necessary) to do so. As a newbie, I need some sage input. Personal opinions are more than welcome, and I hope I am not being too wide open and general with my query.


Among what I intend to create are sites such as:

-Promotional site for my video editing business
-An adventure blog dealing with water related escapes (with affiliate links)
-A blog site dealing with political issues that I may want to eventually upscale into a high traffic forum or community site (if it takes off at some point)
-A site dealing with micro niche health issues
-A somewhat generalized soon to be narrowed down to a more specific niche) site that will encompass health, wealth and happiness subjects (site construction will not begin until I have found my niche)

--I also intend to nurture what works and draws visitors after about 6 months or so, and drop what isn't working in order to spend more time on those sites that do.

--I want to incorporate affiliate links and white hat backlinks whenever possible


---And I want to make sure to the following criteria are met:

MY REQUIREMENTS

-One-time purchase
-Can be used on multiple domains
-Fast loader
-SEO friendly
-Social media/smartphone friendly
-I want to add a forum section to each applicable site that might later be upscaled to become it's own site. I am aware that I may need to purchase my own server and upgrade my hardware to make the transition, and hope that this can be done when the time comes without losing all my forum contributions that have been built up to then when that time comes.

I am not sure what all the solo forum site upgrade entails, and the info I get from an extensive google search seems to be all over the place, from 'cannot be done' to 'it can be done, but will be crazy expensive' to 'can be done without too much pain, and don't let these other posters hard sell you their services by telling you it can't be done without huge investment, or without them personally doing it'

I read very good things about AVADA and Divi, but the overall design and appearance of said themes have not given me the WOW factor. I really DO like the appearance of a lot of what I see on Themeforest, but I have also read bad things about them. Should I just disregard a Wordpress theme altogether and have one custom built from the beginning, or should I start with a Wordpress template since I haven't yet learned to code anything myself yet?

Any help is greatly appreciated, and I thank you in advance for your replies.

Brother Warriors;

I don't want to ask a stupidly general, open ended, non-researched question like "What is the best and most versatile Wordpress theme?" I would like it to be known that I have looked into this exhaustively and I am having a hard time deciding on what WP themes to narrow down and select from. I need opinions right now, because that is what will unfreeze my narrowing process.

I have seen advice here to avoid Themeforest and Envato themes due to lack of support ( I am a newbie, but intend to learn HTML at some point). I would certainly consider paying a lifetime membership for the right theme/set of themes, but I would like to avoid yearly renewal payments if I can possibly avoid it. I read great things about the Genesis framework but the designs I see in the demo do not really grab and excite me.

I am starting several narrow niche sites in several different formats (blog, medical issues, travel, political discussion, video editing business advertisement), all with attached forums (if applicable), and I am hoping to steer them towards AM if possible. I will weed out the chaff when I see what works and what doesn't. I will keep and concentrate on what does work.

Ergo, I would like some experienced, personal opinions on which Wordpress themes you have chosen that do not require yearly renewal, and why you chose them.

Also, for the record, here are a list of my requirements, but I may be focusing on the wrong priorities, so your opinions on my requirements list are welcome as well.

Any help is greatly appreciated....I am so, so stuck in a mental freeze right now...I thank you in advance...
